I was eying the kill a watt for a while, then the price dropped to $20 - I noticed the prices dropped all across the board for these type of units.
Right now it is on my basement freezer - before I put the coal stove down there , it was the coolest spot in the house. For comparision, I'm running it for a week or so in the winter - then again in the summer. (80F vs 65F summer)
I'm sure its more than a 'wash' though. When I put the stove down there - I also put up a clothes line. It is truely amazing how quickly the clothes dry. My wife loves it - they come off the line nice and straight, ready to fold. Plus they are in plain sight - rather than me forgetting to check the dryer. Even with the clothes line, the house humidity is only between 35-40%
Rather than Hi Jack this thread, it would be interesting to start a new thread about energy efficiency - or even a seperate coal forum dealing with efficiency or saving $$$ in the home.
My next stove project is fabbing pin heat exchangers for both sides of the DVC-500 - or at the very least adding blowers to the exisitng panels.
